RHEL 2.1 : pam_smb (RHSA-2003:262)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated pam_smb packages are now available which fix a security
vulnerability (buffer overflow).

The pam_smb module is a pluggable authentication module (PAM) used to
authenticate users using an external Server Message Block (SMB)
server.

A buffer overflow vulnerability has been found that affects unpatched
versions of pam_smb up to and including 1.1.6.

On systems that use pam_smb and are configured to authenticate a
remotely accessible service, an attacker can exploit this bug and
remotely execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2003-0686
to this issue.

Red Hat Enterprise Linux contains a version of pam_smb that is
vulnerable to this issue, however pam_smb is not enabled by default.

Users of pam_smb are advised to upgrade to these erratum packages,
which contain a patch to version 1.1.6 to correct this issue.

Red Hat would like to thank Dave Airlie of the Samba team for
notifying us of this issue.
